To list the contents of the card, first
cd /Volumes/<card name> - in this case
cd /Volumes/phone\ card (the
\ escapes the space). Then you can do
ls -al to list the files (hidden and visible) on the card.
If you want to copy files to somewhere else on the drive, you can use
cp. For example, to copy files to your home directory,
cp <some file> ~ (or to copy everything,
cp -R ./* ~, where * means "match any character(s)" and ~ is short for your home directory (I don't remember the OS X default directory hierarchy).
-R means copy directories recursively (if cp encounters a directory, it should copy the contents of the directory as well).
man cp will tell you more about cp (or any other command).
